PAPER BOX OR PAIL.

SPECIFICATION forming part of Letters Patent No. 377,977, dated Pebruaryl l, 1888. Application filed November 21, 1887. Serial No. 255,775. (Nomodel.) I

To all whom it may concern.-

Be it known that I, STEWART E. BAKER, a

citizen of the United States, and a resident of Binghamton,in the countyof Broome and State of New York, have invented certain new and usefulImprovements in Paper Boxes or Pails; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same,reference being bad to the accompanying drawings,which form a part of this specification, and in which- Figure 1 is aperspective view of my improved paper box or pail complete, showing thebox or pail closed. Fig. 2 is asimilar view showing the box or pailopen. Fig. 3 is a view of the blank forming the box or pail,the folds orcreases upon which the blank is folded being indicated by dotted lines;and Fig. 4 is a perspective View of the blank partly folded at the stageimmediately preceding the finishing of the box or pail.

The same letters of reference indicate corresponding'parts in all thefigures.

My invention has relation to boxes or pails made of paper and foldedfrom one blank into their proper shape; and it consists in the improvedconstruction and combination of parts of such a box or pail, ashereinafter morefully described and claimed.

The blank used for producing the box or pail is a perfectly square pieceof suitably stiff and thick paper, and at the center of this blankasquare bottom, A, is formed by creases a, the said square beingpreferably formed by folding or creasing the blank by means of suitablecreasing-dies adapted for that purpose or over the edges of a mold orshaper having the outlines of the finished box. Four keystone-shapedsides, B, are now formed by side creases, I), having theirn'arrowersides atthe sides of the square bottom, and thetriangularportions 0 between the side edges of the sides have creases a formed atright angles to their bases. When the triangular corner flaps formed byfolding the triangular portions upon their creases are doubled upon theouter or inner sides of the keystone-shaped sides, the box or pail ofFig. 4 is formed.

For the purpose of forming strong places of attachment for the bail D,forming the handle,

opposite sides, are folded upon themselves to form a triple layer, andthe bent and doubled or hook-shaped ends d of the bail are insertedthrough these folded flaps. The triangular flaps F of the two remainingsides are folded the triangular flaps E, which project at two asewing-machine or by hand, so as to firmly 1 secure the six thicknessesof paper forming the two sides.

It will-now be seen that a square and downwardly-tapering box or pail isformed,having a bail'for carrying it. This box or pail is covered byfolding the two free sides of the box or pail over the top so that theinner edges overlap. The two cover portions H carry triangular portionsI of the sides,holding the bail with them,so that the bail will appearsecured in the tops of two triangular ears, thereby holding the coverportions in place without the aid of any separate looking or clampingmechanism.

The triangular side flaps may be doubled both upon the outside of thebox or pail or they may be both doubled upon the inside of the box orpail, according to the character of the contents for which the box orpail is destined, the flaps being folded on the outside when it isdesired to have asmooth inner side for holding partlyfluid contents,while when the box or pail is to be used for solid contents, and it isdesirable to have a smooth or ornamental exterior, the flaps may befolded upon the inside of the box or pail; or it may be filled to thetop without using the cover portions, thus answering the purposes of alarger pail. be folded one upon the outside'and one upon the inside, ifit should be so desired.

By having the cover for the box or pail formed by the upper flaps of twosides being It follows that the flaps may also folded down over the topthe cover is at all comparatively low cost, and will be very simloo pleof construction and comparatively dura ble, and, being perfectly tight,it may be used for carrying fluids or semi-fluid articles when thematerial used in its construction is of sufficient strength anddurability.

The wire bail or'handle may be substituted by a strip of paper, a pieceof string or tape, or any other suitable handle; but the wire bail willbe the most desirable, as it serves as a fastener for the triple-foldedflaps and as a transverse brace for the pail.

Wire staples, as shown in the drawings, are the most desirable fasteningfor the triangular flaps of the cover portions; but any other fasteningmay be employed without departing u from the spirit of the invention.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. A paper box or pail consistingofa square bottom, keystoneshaped sides, doubled triangular corner-flapsdoubled over the sides,cover portions at the tops of two sides, formedwith the'triangnlar upper flaps folded over upon them and folding overthe top of the box or pail, and triangular ears for a handle formed bythe three-ply triangular flaps of the two other sides, having their sideportions doubled in, all constructed of a creased or folded blank, asshown and set forth.

2. A paper box or pail consisting of asquare bottom, keystone-shapedsides, doubled triangular corner-flaps doubled over the sides,coverportions at the tops of two sides,formed with the triangular upper flapsfolded over and se cured by fasteners and folding over the top of thebox or pail, triangular ears formed by three-ply triangular flaps at thetops of the two other sides, and a wire bail having its hook-shaped ordoubled ends inserted through the said ears, all constructed of acreased or folded blank, as shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoalfixed my signature in presence of two witnesses.
